The results showed that: (1) Bioconcentration factor (BCF) values in the liver are more than 500, increasing with the increase of PAHs' molecular weights; so, PAH pollution is a threat to seafood security.

A positive linear relationship beween PAH concentration and organic matter has been demonstrated and the slope of this relationship has been used to identify sites where PAH pollution is generally high.

All sites were found to be affected by diffuse PAH pollution.

To reconstruct a history of polycyclic aromatic hydrocarbon (PAH) pollution in the Gulf of Trieste, one of the largest urbanized areas in the Adriatic Sea, we analyzed three long sediment cores collected between 1996 and 1997.

The data on benzo(a)pyrene (BaP) and other polynuclear aromatic hydrocarbons (PAH) pollution of Lake Peipsi and its tributaries in the 1970s-1980s have been summarized.

The method can be used for the assessment of bioaccessibility involved in the management of polycyclic aromatic hydrocarbon (PAH) pollution.

The distribution of polycylic aromatic hydrorarbons(PAHs) has been determined by authors. The determining methodand results are reported in this article. The measures of reducing the pollution by polycyclic aromatic hydrocarbons are also proposcd.Samples were collected at five xample points in Nanchong city during winter and summer. The method and steps for sample treatmentare: ultrasonic extracting ,suction fitlrating ,vaccum concentrating,purifying with silicagel column ,secondary concantrating and...

The distribution of polycylic aromatic hydrorarbons(PAHs) has been determined by authors. The determining methodand results are reported in this article. The measures of reducing the pollution by polycyclic aromatic hydrocarbons are also proposcd.Samples were collected at five xample points in Nanchong city during winter and summer. The method and steps for sample treatmentare: ultrasonic extracting ,suction fitlrating ,vaccum concentrating,purifying with silicagel column ,secondary concantrating and then dis-solving the sample in definite amount of methanol. The PAHs were separated and determined with high performance. The over-year av-erage concentration of benzo(a)pyrene in air was 31.5ng/m￣3 in Nanchong, it was a little less than that of Chegdu in 1988.The mainsources of PAHs are coal burning and then vehicle exhausting. Changing fuel structure, supplying heat centrically,and strengtheningcity’s traffic control are the main measures of reducing PAH pollution.

Anshan is heavely air polluted city charactorsticed with coalsmorking pollution. This article makes a introductionof some accompolishment under use of liquit chromatograph in the detection of PAH pollution situation of Tsp and dustfall in enviromentair .discover the PAH pollutional distribution regulaton.

An investigation on levels of polycyclic aromatic hydrocarbons (PAHs) in surface water of Xiamen Harbor has been conducted on spring, summer and autumn cruises in 2001 and at six locations. The results showed that the concentration and composition of PAHs in the surface water were variable. The pollution levels of PAHs in April and October were higher than that in July concentrations of total. PAHs in the surface water were mainly dominated by naphthalene (2 rings) in April, acenaphthene (3 rings) in...

The results showed that the concentration and composition of PAHs in the surface water were variable. The pollution levels of PAHs in April and October were higher than that in July concentrations of total. PAHs in the surface water were mainly dominated by naphthalene (2 rings) in April, acenaphthene (3 rings) in July and chrysene (4 rings) in the October. The concentrations of anthracene and benzo(a)pyrene in surface water was higher than the toxicity guidelines. The origin of PAH pollution in surface water of Xiamen Harbor was mostly petrogenic.
